  • Method and apparatus for manufacturing optical elements
    Patent number: 7987015
    Abstract: In a method for producing optical elements, material on a blank (20) is removed with an abrasive liquid jet (32). The liquid jet (32) has a jet thickness (d) which is greater than the dimension (D) of the blank (20) in a plane (E) perpendicular to the direction (R) of the liquid jet. Predefined removal profiles in aspherical form can be achieved by the liquid jet (32) being guided onto the blank (20) at different angles of incidence (?).
    Type: Grant

    Date of Patent: July 26, 2011
    Assignee: Fisba Optik AG
    Inventors: Oliver Fähnle, Wilhelmus Messelink, Mark Meeder
  • Apparatus for Removing Material, Use of Gas Inclusions in an Abrasive Liquid and Process for Grinding and/or Polishing Surfaces
    Publication number: 20080261493
    Abstract: The invention relates to an apparatus for removing material from a surface of a workpiece during grinding and/or polishing of the surface by means of abrasive particles which are delivered by a liquid. The apparatus comprises a device for setting the gas content in the liquid, in particular for adding gas, in particular air, to the liquid.
